We are proposing action on local rules to regulate these emission sources under the Clean Air Act (CAA or "Act"). We are also proposing to approve and conditionally approve the MCAQD's reasonably available control technology (RACT) demonstration for the source categories associated with these rules for the 2008 8-hour ozone national ambient air quality standards (NAAQS) in the Phoenix-Mesa ozone nonattainment area.

ADEQ committed on J…
